OSTexo, bigseb,
Becouse your base shape is simple but made in complex way. It have complex geometry and you could not even join it... So even if client give you sourses in that bad state, you could rebuilt them to get clear geometry. It is not so hard to do.
I can see only one justification for this muddy geometry it is if clien need all that muddy edges and stuff... But I really can not see any reason for client to ask for this? May be I do not know something, tell me :)
